Right now its looking like they got it correct by the 2013. BUT I would wait until those cars that have been garaged for the winter come out of hiding. Then see how many (if any) start to run into top problems.

When 2013 owners say "no problems" does that mean when you put the top down (without the tonneau cover in place) and drive down the highway, you don't see the retracted top flapping in the breeze?

Oh, it still flaps, but the clearance between the top and the rear of the well is much larger on the 13 compared to my 12. The 12 was rubbing against the rear since it was about 1 month old. My 13 still has about 1/2 to 1" clearance from rubbing on the back. I'm going to be watching it on the very hot days this summer though, once the fabric has relaxed further.

Definitely keep an eye on it. My 3rd top took 8 months before the fabric relaxed enough to where it was touching the rear storage well area. When it finally did start touching, it only took a few weeks to start wearing a hole in the material.
